某发动机压气机盘组电子束焊工艺及变形控制

The Electron Beam Welding Technology and Deformation Control of Aeroengine Compressor Disk Group

针对某发动机压气机盘组的焊接变形问题,通过工艺试验,提出了装配间隙控制、夹具刚性固定、焊接工艺优化、电子束局部校形等变形控制措施,实现了一批次压气机盘组的焊接。检测结果表明,焊缝质量及焊后尺寸均满足设计要求。

A series of deformation control measures, such as assembly clearance control, rigid fastening, welding process optimization and local adjustment by electron beam, were developed through welding process experiments. The joint of turbine compressor disks was achieved. Test results showed that welding quality and workpiece dimensions meet design requirements. The welding deformation control measures mentioned in this paper give a reference for welding relative cylinder or shaft parts.
